The National Weather Service warned residents of northern Los Angeles County of a severe storm that could cause flash flooding moving northwest through the afternoon. The warning was in effect through 6:15 p.m. Saturday.
The storm moving in from the mountains of San Diego County during the morning created hit-and-miss rain or hail and widespread lightning all across the Southland.
Although radar showed that most of the storms had moved towards San Luis Obispo by midday, a strong storm moved out of the San Gabriel Mountains into the Antelope Valley at 2 p.m., the NWS said.
The Antelope Valley (14) Freeway was hit hard east of Santa Clarita, as heavy rain fell from Acton to Palmdale. California Highway Patrol officers called for Caltrans road graders to clear the southbound 14 Freeway's Soledad Canyon Road offramp, where 2-3 feet of water and mud was reported, along with a stuck car.
Cars collided and spun out on the muddy freeway near the Palmdale cutoff interchange, CHP officers said.
